About this object
The above color image is a composite Hydrogen Alpha/RGB image of the nebula Sh2-132 in the constellation Cepheus which lies in the Milky Way north of Cygnus. The image was shot using two different scopes. For the Hydrogen Alpha filtered image I used a Stellarvue SV102T refractor. This image was shot during the first quarter moon in early Sept. The RGB images were shot using a Stellarvue SV80ST2 refractor under moonless skies in late Sept. The average sky quality readings were 18.4 during the 1st quarter moon(Ha) and 19.6 during moonless skies (RGB).
